The LBE Unlimited ARGTR rifle length gas tube is a straightforward, dependable replacement or upgrade part for your AR-15 platform rifle. Built from 304 stainless steel seamless tubing, this gas tube channels propellant gases from your barrel to the bolt carrier group—a critical component in your rifle's operating system. Whether you're troubleshooting a malfunctioning gun, upgrading from a worn original part, or building from the ground up, a quality gas tube ensures reliable cycling and longevity. LBE Unlimited's stainless construction resists corrosion and withstands the heat cycles of sustained shooting, making it a solid choice for hunters, competition shooters, and general-purpose AR owners who want parts that simply work.
This rifle-length tube fits the standard AR-15 platform and ships complete with the gas tube roll pin needed for installation. Stainless steel construction means less maintenance headache and better durability than mild steel alternatives, especially if you're shooting corrosive ammunition or storing your rifle in less-than-ideal conditions. Made in the USA, it reflects the kind of practical engineering that keeps your rifle running downrange.
If you're replacing a bent, damaged, or fouled gas tube, or assembling an upper receiver from parts, this LBE Unlimited tube delivers the reliability you need without unnecessary complexity or cost.

Yes—this is a rifle-length gas tube designed for the standard AR-15 platform. Confirm that your upper receiver calls for a rifle-length tube (not mid-length or pistol-length) before ordering.
304 stainless steel resists rust and corrosion better than standard steel, so your gas tube stays cleaner and lasts longer, even with corrosive ammunition or humid storage conditions.
The kit includes the gas tube and the roll pin required to secure it to your barrel.
A gas tube may need replacement if it's bent, cracked, heavily fouled, or if your rifle is not cycling properly due to gas system malfunction. It's also a common part to buy when building an upper receiver from components.
